A doctor recently had a patient drop in on him for an unscheduled appointment. "What can I do for you today?" the doctor asked. The older gentleman replied, "Doctor, you must help me. Every time I make love to my wife, my eyes get all bleary, my legs go weak, and I can hardly catch my breath. Doc, I'm scared!" The doctor, looking at his 86-year-old patient, said, "These sensations tend to happen over time, especially to a man of your advanced years, but tell me, when did you first notice these symptoms?" The old guy's response was, "Well, three times last night, and twice again this morning!"
